The Voice's first official couple tried to hide their flirtation at last week's live rounds, but this week, they couldn't keep their hands off each other!

Blake Shelton and Gwen Stefani's romance has been the talk of the town since before they even made it official on November 4th right before the CMAs.

Last night when the coaches were being introduced at the beginning of the show (not seen on TV), Stefani danced her way in, then jumped into Shelton's arms as the entire audience said, "Awwwww!" He even picked her up and swung her around a little bit. Too cute.

During the show, contestant Amy Vachal sang a sultry acoustic version of Drake's "Hotline Bling", which is also the song that Stefani and Shelton sang together at The Tonight Show Starring Jimmy Fallon in October.

Completely amazed by the performance, Shelton said, "I don’t think there’s ever been a more elegant and classy performance of a song about a booty call in the history of music."

"You know that song?" Adam Levine asked, to which Shelton quickly responded, "Gwen sang it to me on the Tonight Show one night, so…”

Pharrell couldn't stop giggling, Levine started to fan himself, and Stefani was blushing and flustered! Guess it was getting steamy in there!

Apparently the couple couldn't get off set faster, as they, "sprinted backstage together."
